Abstract: The solvent extraction-differential pulse stripping voltammetry method was developed to determine O-phenlyphenol (OPP) in orange peel. In order to avoid the influence of ascorbic acid and essential oil, OPP was extracted by toluene from orange peel. Under the optimal conditions, differential pulse stripping voltammetry was used to determine OPP in orange peel. The results demonstrated that the oxidative peak current of OPP was linearly correlated with the OPP concentrations in the range of 2.0 × 10-9 -4.0 × 10-6 mol/L. The detection limit and recovery rate of this developed method were 8.1 × 10-10 mol/L and 106.7%-112.2%, respectively. Therefore, this developed method is characteristics of simple operation, fast detection, high sensitivity and accuracy.
